[0031] Please refer to Figures 1 to 5As shown in the figure, an embodiment of the present utility model provides a centrifuge device for medical testing, including a centrifuge main body 1, a fixing structure 3, and a cover plate 2. The centrifuge main body 1 is a hollow structure, and a motor is installed inside the centrifuge main body 1. Four anti-slip blocks are fixedly connected to the bottom of the centrifuge main body 1 to prevent the centrifuge main body 1 from shaking during use. The fixing structure 3 is arranged inside the centrifuge main body 1. The fixing structure 3 includes a placement frame 306 arranged inside the centrifuge main body 1. The placement frame 306 is a cylindrical hollow structure, and square openings are provided on both sides of the placement frame 306. Fixed blocks 305 are slidably connected to both sides of the placement frame 306. One side of the fixed block 305 is a curved surface, and a rubber pad is arranged at the curved surface of the fixed block 305 to ensure the stability after the test tube is fixed. A connecting rod 304 is hinged to the fixed block 305 on the other side of the placement frame 306. When the connecting rod 304 rotates, it can drive the fixed block 305 to move horizontally. An adjusting plate 303 is hinged to the bottom end of the connecting rod 304. When the adjusting plate 303 moves up and down, it can drive the connecting rod 304 to rotate, thereby driving the fixed block 305 to move horizontally.

[0032] Example 2 :

[0033] Please refer to Figures 1 to 5As shown, based on the first embodiment, the present application further provides a fixing structure 3. The fixing structure 3 includes a fixing frame 301 fixedly arranged at the motor output end of the centrifuge main body 1. The fixing frame 301 is in the shape of a hollow cylinder. By starting the motor inside the centrifuge main body 1, the fixing frame 301 can be driven to rotate. A threaded rod 302 is rotatably connected above the fixing frame 301. One end of the threaded rod 302 is fixedly connected to a turntable. By rotating the turntable, the threaded rod 302 can be driven to rotate. A square rod 307 is fixedly arranged inside the fixing frame 301. The bottom of the square rod 307 is connected to the inner bottom of the placement frame 306 by welding, improving the stability of the overall structure. The placement frame 306 is fixedly arranged inside the placement frame 306. The bottom of the placement frame 306 is bolted to the inner bottom of the placement frame 306, facilitating subsequent disassembly and maintenance by the staff using tools. A threaded hole matching the threaded rod 302 is provided at the center of the adjusting plate 303, and the threaded rod 302 is threadedly connected to the threaded groove of the adjusting plate 303. By rotating the threaded rod 302, the adjusting plate 303 can be driven to move vertically under the influence of the thread. The adjusting plate 303 is slidably connected to the square rod 307. The square rod 307 can limit the adjusting plate 303 to ensure the stability of the adjusting plate 303 during movement. A sliding groove is provided on one side above the fixing frame 301. The adjusting plate 303 is slidably connected to the placement frame 306. The adjusting plate 303 is provided with a circular hole. The placement frame 306 passes through the circular hole, and the diameter of the circular hole is larger than the diameter of the placement frame 306 to prevent the placement frame 306 from affecting the movement of the adjusting plate 303. A sliding sleeve 308 is fixedly arranged on one side of the square rod 307. A sliding rod 309 is slidably connected to the sliding sleeve 308, and the sliding rod 309 is fixedly connected to the fixing block 305. The fixing block 305 is limited by the cooperation of the sliding rod 309 and the sliding sleeve 308 to ensure the stability of the fixing block 305 during movement. There are six groups of placement frames 306 in total. The six groups of placement frames 306 have the same shape and size and are evenly distributed inside the fixing frame 301. By providing six groups of placement frames 306, six test tubes can be fixed for experiments simultaneously, which is convenient and fast.

[0034] Example 3 :

[0035] Please refer to Figures 1 to 5As shown in the figure, based on the first and second embodiments, the present application further provides a limiting structure 4, which is arranged above the fixed frame 301. The limiting structure 4 includes a limiting block 401 arranged above the fixed frame 301. One side of the limiting block 401 is in a curved surface shape, and a rubber pad is arranged at the curved surface shape to increase the friction force through the rubber pad and ensure the stability after the threaded rod 302 is fixed. A spring 402 is fixed on one side of the limiting block 401, and the spring 402 is in a slightly compressed state. A pulling block 403 is fixed above the limiting block 401. The movement of the pulling block 403 can drive the limiting block 401 to perform the same movement. The limiting block 401 is slidably connected to the sliding groove of the fixed frame 301, and both sides of the limiting block 401 are in contact with the inner wall of the sliding groove. One end of the spring 402 is in contact with the inner wall of the sliding groove of the fixed frame 301. By arranging the spring 402, the limiting block 401 can be pushed to move, so that the limiting block 401 can quickly return to the initial position to fix the threaded rod 302. A limiting rod 404 is slidably connected to one side of the limiting block 401, and the limiting rod 404 is fixedly connected to the inner wall of the sliding groove of the fixed frame 301. The limiting rod 404 can limit the limiting block 401 to ensure the stability of the limiting block 401 during the movement process. And the limiting rod 404 passes through the central hole of the spring 402, and the limiting rod 404 can limit the spring 402 to avoid the situation of deformation and dislocation of the spring 402.

[0036] The specific working principle of the present utility model is as follows: First, when it is necessary to fix the test tube, insert the test tube into the placement frame 306, and then pull the pulling block 403. The movement of the pulling block 403 drives the movement of the limiting block 401. The movement of the limiting block 401 causes the spring 402 to deform. The movement of the limiting block 401 separates from the turntable of the threaded rod 302. Then, while keeping pulling the limiting block 401, rotate the threaded rod 302;

[0037] Secondly, since the threaded rod 302 is threadedly connected to the adjusting plate 303, and the adjusting plate 303 is slidably connected to the square rod 307, when the threaded rod 302 rotates, under the influence of the thread, it will drive the adjusting plate 303 to move upward. Since one end of the adjusting plate 303 is hinged to one end of the connecting rod 304, the other end of the connecting rod 304 is hinged to the fixed block 305, and the fixed block 305 is slidably connected to the placement frame 306. Therefore, the upward movement of the adjusting plate 303 will drive the connecting rod 304 to rotate. The rotation of the connecting rod 304 will drive the fixed block 305 to move inward to the inner side of the placement frame 306. The movement of the fixed block 305 fits against the outer wall of the test tube. The fixed block 305 can fix test tubes of different sizes to avoid the situation of shaking during the centrifugation of the test tube;

[0038] Finally, after the test tube is fixed, release the pulling block 403, and the spring 402 will restore its deformation to push the limit block 401 to move. The movement of the limit block 401 drives the rubber pad on one side to fit against the turntable side of the threaded rod 302, and the threaded rod 302 is fixed by the limit block 401, avoiding the loosening of the threaded rod 302 during centrifugation and ensuring the stability after the test tube is fixed.

[0039] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and the present utility model can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model.
